ENZYME entry: EC

Accepted Name
Ginsenoside Rb1 beta-glucosidase.
Reaction catalysed
Ginsenoside Rb1 + 2 H(2)O <=> ginsenoside Rg3 + 2 D-glucopyranose
  • Ginsenosidases catalyze the hydrolysis of glycosyl moieties attached to the C-3, C-6 or C-20 position of ginsenosides.
  • They are specific with respect to the nature of the glycosidic linkage, the position and the order in which the linkages are cleaved.
  • Ginsenoside Rb1 beta-glucosidase specifically and sequentially hydrolyzes the 20-(beta-D-glucopyranosyl-(1->6)-beta-D glucopyranosyloxy) residues attached to position 20 by first hydrolyzing the (1->6)-glucosidic bond to generate ginsenoside Rd as an intermediate, followed by hydrolysis of the remaining 20-O-beta-D- glucosidic bond.
